KENYA , a See also:great volcanic See also:mountain in See also:British See also:East See also:Africa, situated just See also:south of the See also:equator in 370 20' E. It is one of the highest mountains of Africa, its highest See also:peak reaching an See also:altitude of 17,007 ft. (with a possible See also:error of 30 ft. either way). The central core, which consists of several steep pyramids, is that of a very denuded old See also:volcano, which when its See also:crater was See also:complete may have reached 2000 ft. above the See also:present See also:summit. Lavas See also:dip in all directions from the central crystalline core, pointing to the conclusion that the See also:main portion of the mountain represents a single volcanic See also:mass. From the central peaks, of whichthe See also:axis runs from W.N.W. to S.S.E., ridges radiate outwards, separated by broad valleys, ending upwards in vast cirques. The most important ridges centre in the peak Lenana (16,300 ft.) . at the eastern end of the central See also:group, and through it runs. the See also:chief See also:water-parting of the mountain, in a generally See also:north to south, direction. Three main valleys, known respectively as Hinde, See also:Gorges and Hobley valleys, run down from this to the east, and four—Mackinder, Hausberg, Teleki and Hohnei—to the See also:west. From the central peaks fifteen glaciers, all lying west of the main See also:divide, descend to the north and south, the two largest being the See also:Lewis and See also:Gregory glaciers, each about 1 in. See also:long, which, with the smaller Kolb See also:glacier, See also:lie immediately west of the maindivide. Most of the glaciers terminate at an altitude of 14,800–14,900 ft., but the small Cesar glacier, drained to, the Hausberg, valley, reaches to 14,450. Glaciation was formerly much more extensive, old moraines being observed down to 12,000 ft. In the upper parts of the valleys a number of lakes occur, occupying hollows and See also:rock basins in the agglomerates and ashes, fed by springs, and feeding many of the streams that drain the mountain slopes. The largest of these are LakeHohnei, lying at an altitude of 14,000 ft., at the See also:head of the valley of the same name, and measuring 600 by 400 yds..; and See also:Lake Michaelson (12,700 ft.?) in the Gorges; Valley. At a distance from the central core the radiating ridges become less abrupt and descend with a See also:gentle gradient, finally passing somewhat abruptly, at a height of some 7000 ft., into the level See also:plateau. These See also:outer slopes are clothed with dense See also:forest and See also:jungle, composed chiefly of junipers and Podocarpus, and' between 8000 and 9800 ft. of huge bamboos. The forest See also:zone extends to about 10,500 ft., above which is the steeper alpine zone, in which pasturages alternate with rocks and crags. This extends to- a See also:general height of about 15,000 ft., but in See also:damp, sheltered valleys the pasturages extend some distance higher. The only trees or shrubs in this zone are the See also:giant Senecio (See also:groundsel) and See also:Lobelia, and See also:tree-heaths, the Senecio forming groves in the upper valleys. Of the See also:fauna of the See also:lower slopes, tracks of See also:elephant, See also:leopard and See also:buffalo have been seen, between 11,500 and 14,500 ft. That of the alpine zone includes two See also:species of dassy ( Procavia) , a coney (Hyrax); and a See also:rat (Otomys) The See also:bird fauna is of considerable See also:interest] the finest species of the upper zone being an See also:eagle-See also:owl, met with at 14,000 ft. At 11,000 ft. was found a See also: It was first seen, from;a distance, by the missionary See also:Ludwig Krapf in 1849; approached from the west by See also:Joseph See also:Thomson in 1883; partially ascended by See also:Count S. Teleki (1889), J. W. Gregory (1893) and Georg Kolb (1886); and its summit reached by H. J. Mackinder in 1899. See J. W. Gregory, The Great Rift-Valley (See also:London, 1896) H. 'J. Mackinder, " See also:Journey to the Summit of Mount Kenya," Geog. Jndl., May 1900. (E. Additional information and CommentsThere are no comments yet for this article.
